Galactosemia is generally diagnosed in neonates after symptoms are shown or during routine newborn screening. However, there have been rare cases of undiagnosed galactosemia in adults, usually presenting with developmental delay in addition to numerous other symptoms. [6]
In classic galactosemia, galactose-1-phosphate uridylyltransferase activity is reduced or absent; leading to an accumulation of the precursors, galactose, galactitol, and Gal-1-P. [3] The elevation of precursors can be used to differentiate GALT deficiency from galactokinase deficiency, as Gal-1-P is typically not elevated in galactokinase ...
Galactose epimerase deficiency, also known as GALE deficiency, Galactosemia III [1] and UDP-galactose-4-epimerase deficiency, [2] is a rare, autosomal recessive form of galactosemia associated with a deficiency of the enzyme galactose epimerase.
Unlike classic galactosemia, which is caused by a deficiency of galactose-1-phosphate uridyltransferase, galactokinase deficiency does not present with severe manifestations in early infancy. Its major clinical symptom is the development of cataracts during the first weeks or months of life, as a result of the accumulation, in the lens, of ...
Duarte variant galactosemia, DG, or Biochemical variant galactosemia) Leloir metabolic pathway: Galactose-1Puridylyltransferase (GALT, red font) is the middle enzyme in the Leloir pathway of galactose metabolism.
The treatment for galactosemic cataract is no different from general galactosemia treatment. In fact, galactosemic cataract is one of the few symptoms that is actually reversible. Infants should be immediately removed from a galactose diet when symptoms present, and the cataract should disappear and visibility should return to normal. [12]
Deficiency of GALT causes classic galactosemia. Galactosemia is an autosomal recessive inherited disorder detectable in newborns and childhood. [12] It occurs at approximately 1 in every 40,000-60,000 live-born infants.
Is the most problematic, as galactose-free diets are not effective in treating neurocognitive deficiencies (in particular language disorders such as verbal dyspraxia) and ovarian failure. If a galactose-free diet is administered, cataracts and acute symptoms such as kidney and liver failure respond immediately.
